A multiphase inverter has two card shaped arm modules facing each other along a stacking direction. Each module has semiconductor switching elements disposed along an element arranging direction substantially perpendicular to the stacking direction, a common heat sink plate connecting direct current electrodes of the elements with one of terminals of the power source, and phase heat sink plates connecting respective alternating current electrodes of the elements with respective multiphase terminals of a motor. The elements of each module correspond to all phases of an alternating current. Each common heat sink plate forms a principal surface of the corresponding module, and the phase heat sink plates of each module forms another principal surface. The principal surfaces of each module face each other along the stacking direction.

Printed antenna devices are provided, which can operate at RF and microwave frequencies, for example, while simultaneously providing antenna performance characteristics such as high gain/directivity/radiation efficiency, high bandwidth, hemispherical radiation patterns, impedance, etc., that render the antennas suitable for voice communication, data communication or radar applications, for example. Further, apparatus are provided for integrally packaging such printed antenna devices with IC (integrated circuit) chips (e.g., transceiver) to construct IC packages for, e.g., wireless communications applications.

The present invention relates to photovoltaic power systems., photovoltaic concentrator modules, and related methods. In particular, the present invention features concentrator modules having interior points of attachment for an articulating mechanism and/or an articulating mechanism that has a unique arrangement of chassis members so as to isolate bending, etc. from being transferred among the chassis members. The present invention also features adjustable solar panel mounting features and/or mounting features with two or more degrees of freedom. The present invention also features a mechanical fastener for secondary optics in a concentrator module.

The present invention relates to tableware. The tableware includes a handle and a holding section connected with the handle. The cross-section of the handle is “M”-shaped, with a “V”-shaped groove extending from the middle of the handle to the holding section, and at least one V-shaped groove being positioned in the middle of the holding section. The above-mentioned parts make up the strengthened tableware. The “M”-shaped and “W”-shaped grooves strengthen the handle, the palm and the finger of the tableware. On the other hand, the manufacturing and concave points located at the “M”-shaped groove of the front surface and the “W”-shaped groove of the back surface of the tableware enable the tableware to overlap closely and steadily because of a parallel-wave structure principle. Different types or the same type of tableware can overlap closely.

A freestanding back therapy and multiple exercise station on which various therapeutic, stretching, bending, twisting, extension and inversion exercises may be carried out utilizing the user's weight for fully flexing and decompressing the spine and strengthening the trunk and back muscles of the user. The station has a frame of tubular construction with a floor engaging base, front and rear vertical upright members, a horizontal top member extending between upper ends thereof, and a cushioned forearm pad on each said horizontal member with handgrips at outer of the horizontal top members. A lower pair of vertically spaced padded cross members extend transversely between the rear vertical upright members to serve as foot supports. A central upright member is connected at a lower end with at least one padded cross member and has a forward and angularly upward extending upper portion. A backrest pad is mounted the central upright member. An upper pair of parallel vertically spaced padded tubular members extend laterally outward from each side of the central upright member near its upper portion to selectively serve either as handgrips or as elevated or leg or foot supports when performing exercises. A removable rotatable cylindrical cushioned roller is may be mounted transversely between the horizontal top members to serve as a back engaging roller or a seating surface when performing exercises. Various auxiliary exercise apparatus may be removably connected with the station for performing a variety of exercises.

This invention provides a thermal energy battery having an insulated tank contains a multitude of densely packed plastic tubes filled with a phase-change material (PCM, such as ice) that changes from solid to liquid and vice-versa. Energy is stored when the PCM transitions from liquid to solid form, and released when the PCM transitions back from solid to liquid form. The tubes are arranged vertically, span the height of a well-insulated tank, and are immersed in heat transfer fluid (HTF) contained within the tank. The HTF is an aqueous solution with a freezing point temperature below the freezing point temperature of the chosen PCM. The HTF remains in liquid form at all times during the operation of the battery. Diffusers located allow the HTF to be extracted uniformly from the tank, pumped and cooled by a liquid chiller situated outside the tank and then and inserted back into the tank.

The invention discloses a preparation method of a mixed filling type thermal conductive silicone rubber composite. Raw materials comprises the following components, by mass, 100 parts of raw silicone rubber, 10 parts of white carbon black, 1 to 3 parts of hydroxy silicone oil, 100 to 200 parts of a thermal conductive filler, 2 to 4 parts of a silane coupling agent and 2 parts of a di-2,5-vulanizator. The preparation method comprises the following steps: adding raw silicone rubber to a double roller mill; adding white carbon black, the thermal conductive filler, the silane coupling agent and hydroxy silicone oil according to a formula design after roller packaging; adding a peroxide vulcanizer after repeatedly and uniformly mixing; mixing uniformly to obtain mixed silicone rubber; putting in a die and carrying out first-stage vulcanization after cold pressing mold filling; and putting a molded sample in an air blasting drier and carrying out second-stage vulcanization to obtain a finished product. In the present invention, mixed particles of SiC and AlN are employed to fill high temperature vulcanized silicon rubber, effective thermal conductive net chains are formed in silicone rubber matrixes, so the obtained heat-conducting silicone rubber composite material has a good heat conducting performance.

Disclosed herein is a device for housing a plurality of electrochemical cells, wherein the housing provides stability, temperature control and maximum packing density. The battery module housing comprises a first semi-enclosure and a second semi-enclosure, wherein the first and second semi-enclosure are aligned to form compartments there between. Each compartment is designed to accommodate at least one electrochemical cell, such as a cylindrical battery or a prismatic battery. Each semi-enclosure comprises an interior wall and an exterior wall. The interior and exterior wall align together to form a flow path between the walls through which coolant or any other thermal management medium may flow. The coolant enters the semi-enclosure through a coolant inlet, flows between the interior and exterior walls; then flows out of the semi-enclosure through a coolant outlet.

A pillow device having a pillow portion with a main head support section for supporting the head, and at least one eye mask portion for covering the eyes of the user. For additional comfort, a neck support may be removably attached to the pillow device to provide not only support for the head, but also support for the neck. Because of the overall shape of the pillow device can easily simulate a doll, a skirt with popping out figures may be added to simulate an angel or other favorite figures with open arms to welcome the user. Moreover, the pillow device may function as a computer pad holder and a bag.
